Cataclysm as a musclebond Catatonian who acts as the main antagonist of the rebooted "Biker Mice From Mars" series - alongside his "comic relief" right-hand Hairball and human ally Ronaldo Rump.

Although Cataclysm is by far the most competent of the trio he is still rather dense as villains go and is by no means a master at his work, in fact Catatonian high-command regard both him and Hairball as failures more often than not.

Regardless of this Cataclysm remains, arguably, the main antagonist of the trio of Martian Mice on Earth and is relentless in his pursuit of the Regenerator: he is also extremely strong and powerful, though nowhere near a match for the mice in a fair fight.
